NON-COMMERCIAL SOURCE CODE LICENSE AGREEMENT \
\n\n \
Software: ChemPathTool \
\n \
Version: 1.0 \
\n\n \
IMPORTANT - READ CAREFULLY: \
\n \
This License Agreement ("Agreement") is a \
legal agreement between you (in your capacity as an individual and as \
an agent for your company, institution or other entity) and The \
Regents of the University of California, Department of Energy \
contract-operators of the Ernest Orlando Lawrence Berkeley National \
Laboratory ("Berkeley Lab"). Downloading, installing, using, or \
copying of the Software (as defined below) by you or by a third party \
on your behalf indicates your agreement to be bound by the terms and \
conditions of this Agreement. If you do not agree to these terms and \
conditions, do not download, install or use the Software. \
\n\n \
1. LICENSE GRANT. Berkeley Lab grants you, and you hereby accept, a \
non-exclusive, royalty-free perpetual license to install, use, modify, \
prepare derivative works, incorporate into other computer software, \
and distribute the version noted above of the computer software \
program noted above, in binary and source code format, or any \
derivative work thereof, together with any associated media, printed \
materials, and on-line or electronic documentation (if any) provided \
by Berkeley Lab (collectively, the "Software") for non-commercial \
research and development purposes only, subject to the following terms \
and conditions: (i) any distribution of the Software shall bind the \
receiver to the terms and conditions of this Agreement; (ii) any \
distribution of the Software in modified form shall clearly state that \
the Software has been modified from the version originally obtained \
from Berkeley Lab. This version of the Software constitutes a \
research prototype and may be changed substantially. The license \
grant set forth above is subject to receipt by Berkeley Lab of any \
required U.S. Department of Energy approvals. \
\n\n \
2. COPYRIGHT; RETENTION OF RIGHTS. The above license grant is \
conditioned on the following: (i) you must reproduce all copyright \
notices and other proprietary notices on any copies of the Software \
and you must not remove such notices; (ii) in the event you compile \
the Software, you will include the copyright notice with the binary in \
such a manner as to allow it to be easily viewable; (iii) if you \
incorporate the Software into other code, you must provide notice that \
the code contains the Software and include a copy of the copyright \
notices and other proprietary notices. All copies of the Software \
shall be subject to the terms of this Agreement. Subject to approval \
by the U.S. Department of Energy: (a) you hereby acknowledge that the \
Software is protected by United States copyright law and international \
treaty provisions; (b) Berkeley Lab, and its licensors (if any), \
hereby reserve all rights in the Software which are not explicitly \
granted to you herein; (c) without limiting the generality of the \
foregoing, Berkeley Lab and its licensors retain all title, copyright, \
and other proprietary interests in the Software and any copies \
thereof, and you do not acquire any rights, express or implied, in the \
Software, other than those specifically set forth in this Agreement. \
\n\n \
3. NO MAINTENANCE OR SUPPORT; TREATMENT OF ENHANCEMENTS YOU CHOOSE TO \
PROVIDE TO BERKELEY LAB. Berkeley Lab is under no obligation \
whatsoever to: (i) provide maintenance or support for the Software; or \
(ii) to notify you of bug fixes, patches, or upgrades to the features, \
functionality or performance of the Software ("Enhancements") (if \
any), whether developed by Berkeley Lab or third parties. If, in its \
sole discretion, Berkeley Lab makes an Enhancement available to you \
and Berkeley Lab does not separately enter into a written license \
agreement with you relating to such bug fix, patch or upgrade, then it \
shall be deemed incorporated into the Software and subject to this \
Agreement. You are under no obligation whatsoever to provide any \
Enhancements to Berkeley Lab or the public that you may develop over \
time; however, if you choose to provide your Enhancements to Berkeley \
Lab, or if you choose to otherwise publish or distribute your \
Enhancements, in source code form without contemporaneously requiring \
end users or Berkeley Lab to enter into a separate written license \
agreement for such Enhancements, then you agree to promptly provide \
such Enhancements to Berkeley Lab and you hereby grant Berkeley Lab a \
non-exclusive, royalty-free perpetual license to install, use, modify, \
prepare derivative works, incorporate into the Software or other \
computer software, distribute, and sublicense your Enhancements or \
derivative works thereof, in binary and source code form. \
\n\n \
4. U.S. GOVERNMENT RIGHTS. The Software was developed under funding \
from the U.S. Department of Energy and the U.S. Government \
consequently retains certain rights as follows: the U.S. Government \
has been granted for itself and others acting on its behalf a paid-up, \
nonexclusive, irrevocable, worldwide license in the Software to \
reproduce, prepare derivative works, and perform publicly and display \
publicly. Beginning five (5) years after the date permission to \
assert copyright was granted by the U.S. Dept. of Energy, and subject \
to any subsequent five (5) year renewals, the U.S. Government is \
granted for itself and others acting on its behalf a paid-up, \
nonexclusive, irrevocable, worldwide license in the Software to \
reproduce, prepare derivative works, distribute copies to the public, \
perform publicly and display publicly, and to permit others to do so. \
\n\n \
5. WARRANTY DISCLAIMER. THE SOFTWARE IS SUPPLIED "AS IS" WITHOUT \
WARRANTY OF ANY KIND. BERKELEY LAB, ITS LICENSORS, THE UNITED STATES, \
THE UNITED STATES DEPARTMENT OF ENERGY, AND THEIR EMPLOYEES: (1) \
DISCLAIM ANY WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED \
TO ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR \
PURPOSE, TITLE OR NON-INFRINGEMENT, (2) DO NOT ASSUME ANY LEGAL \
LIABILITY OR RESPONSIBILITY FOR THE ACCURACY, COMPLETENESS, OR \
USEFULNESS OF THE SOFTWARE, (3) DO NOT REPRESENT THAT USE OF THE \
SOFTWARE WOULD NOT INFRINGE PRIVATELY OWNED RIGHTS, (4) DO NOT WARRANT \
THAT THE SOFTWARE WILL FUNCTION UNINTERRUPTED, THAT IT IS ERROR-FREE \
OR THAT ANY ERRORS WILL BE CORRECTED. \
\n\n \
6. LIMITATION OF LIABILITY. IN NO EVENT WILL BERKELEY LAB OR ITS \
LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, \
SPECIAL OR PUNITIVE DAMAGES OF ANY KIND OR NATURE, INCLUDING BUT NOT \
LIMITED TO LOSS OF PROFITS OR LOSS OF DATA, FOR ANY REASON WHATSOEVER, \
WHETHER SUCH LIABILITY IS ASSERTED ON THE BASIS OF CONTRACT, TORT \
(INCLUDING NEGLIGENCE OR STRICT LIABILITY), OR OTHERWISE, EVEN IF \
BERKELEY LAB HAS BEEN WARNED OF THE POSSIBILITY OF SUCH LOSS OR \
DAMAGES. IN NO EVENT SHALL BERKELEY LABS LIABILITY FOR DAMAGES \
ARISING FROM OR IN CONNECTION WITH THIS AGREEMENT EXCEED THE AMOUNT \
PAID BY YOU FOR THE SOFTWARE. \
\n\n \
7. INDEMNITY. You shall indemnify, defend, and hold harmless Berkeley \
Lab, the U.S. Government, the Software developers, the Software \
sponsors, and their agents, officers, and employees, against any and \
all claims, suits, losses, damage, costs, fees, and expenses arising \
out of or in connection with this Agreement. You shall pay all costs \
incurred by Berkeley Lab in enforcing this provision, including \
reasonable attorney fees. \
\n\n \
8. TERM AND TERMINATION. The license granted to you under this \
Agreement will continue perpetually unless terminated by Berkeley Lab \
in accordance with this Agreement. If you breach any term of this \
Agreement, and fail to cure such breach within thirty (30) days of the \
date of written notice, this Agreement shall immediately \
terminate. Upon such termination, you shall immediately cease using \
the Software, return to Berkeley Lab, or destroy, all copies of the \
Software, and provide Berkeley Lab with written certification of your \
compliance with the foregoing. Termination shall not relieve you from \
your obligations arising prior to such termination. Notwithstanding \
any provision of this Agreement to the contrary, Sections 5 through 11 \
shall survive termination of this Agreement. \
\n\n \
9. EXPORT CONTROLS. You shall observe all applicable United States and \
foreign laws and regulations (if any) with respect to the export, \
re-export, diversion or transfer of the Software, related technical \
